Disappointing
Works but not great with a silicone number case. Impossible to keep bubbles out

GlassFusion+ Screen Protector Apple Watch
If this works as well as the Zagg screen protector for my iPhone, which has fallen on concrete several times and still has no scratches, this GlassFusion+ Screen Protector for Apple Watch will prove to be a worthwhile investment!

Best simple screen protector yet...
I am a minimalist, which is why I purchased a 40mm Apple Watch. Since my priority is a small, sleek watch, the last thing I want is a big, bulky screen protector or bumper shroud. I have been on a quest to find the most minimal screen protector that provides maximum protection. Initially, I found a well-fitting, inexpensive glass protector I liked, but it was so fragile that I shattered four in a month and a half. I then found an expensive, VERY sturdy plastic screen protector, but it was too thick, with rough edges, and peeled off in the first week. After finally finding and using the InvisibleShield (it's in the name!) GlassFusion+ screen protector, I have realized it's the perfect FUSION (pun intended) of the two aforementioned protectors. It is the perfect fit, with tapered edges that so far haven't caught on anything, and is a mix of glass and plastic, which leads me to assume it is less likely to shatter.

Glass screen protector
I’ve tried other screen protectors and they always pop off and zag has stayed on since I’ve put it on my watch

NOT HAPPY WITH SHIELD
I really think the quality of this item is subpar. I had the original InvisbleShield when Apple watch first came out, the shield was glass like for the phones, now they are this flimsy plastic. They really don't stick well, even following the directions to a T. Not a lot of choices out there. I bought the more expensive Shield because the one I needed to replace was not in stock, for months. I was expecting a better quality Shield and it wasn't any different than the one I removed, and it cost $20.00 more. Not happy with this item.

Made my phone look new
So far so good, was hoping for something a little more glass like. As long as it protects my screen and they warranty like they have in the past for me, I will have no concerns.

ZAGG always the best but…
Excellent product, installation remains challenging-guide holes don’t match phone!

Bubbles
They say it is easy to install but the directions are not as clear as they make it and the bubbles do not press out easily. I prefer the old solid glass protectors that are rigid..

Poor design
Can not get the bubbles to go away. Get them all pushed out and they are all back within seconds.

Not happy
Didn't adhere on the sides. I have used Zagg for years and this is the 1st time I'm disappointed.

Great product
It is easy to apply, just difficult to get it perfectly centered up even with the guide. Beyond that it is great and taking a beating every day like a champ

Zagg, glass fussing is great.
I am hard on phone screens but since I've been using Zagg Glass fusion I've no even cracked, chipped nor broken a screen. And Zagg stands behind there warranty, no hassle, just register your product after purchase. Best screen protector out there, my true feelings.
